Jewel by Lisa and Jil Sander do the Hats and Holes trend.

A few weeks back in New York, Jewel by Lisa showcased her S/S 2012 collection. With her tribute to Vintage Nigeria, the models wore African traditional hats. Recently in Milan, Jil Sander also showcased her S/S 2012 collection and the models were seen wearing African-Inspired hats very much similar to those on the runway at JBL. Also notice that the fabrics of the pieces both have holes.
Go Lisa! Africa is proud of you.
